ABSTRACT:
A device is taught for holding a sew cord or corded piping while it is cut and for manufacturing sew cord with a desired seam allowance. The device incorporates an adjustable seam allowance by providing notches cut for holding the sew cord after or during stitching and during the cutting of the seam allowance. Various methods of adjusting the length of the seam and automating the process include having variable distance cuts, having a reduced side for tracking a cutting blade incorporating the device into a presser and incorporating a cutting blade in the product.
